Idk know ladies... Haven't felt the baby move, I've called my OB and she wants me to write Dow how long and far apart these Braxton Hicks are... I'm at work so I can't lay down I just have a BIG glass of ice cold water.. I'm going to freak out if I don't feel him move... Idk if I should just go to the hospital or just call her back an about 30mins
